【 摘 要 】

One method of metal welding is a solid-state incorporation process, namely friction stir welding (FSW). This technique can be used on materials that are difficult to weld with fusion welding processes. Among the benefits of FSW are reducing distortion, eliminating solidification, saving energy and being environmentally friendly. This research investigates the effect of three different transverse speeds at 1.2, 2.4 and 3.6 (mm / s) on the hardness, tensile and micro structure properties of friction stir welds of AA6061-T651 plates. The research result find that the micro hardness and strength increase when the transverse speeds are increase. The micro structure showed that the grain size more smaller by increase the transverse speeds.
